- 返回名为 time（以 UTC 为单位）的列，作为 Unix 时间戳或任何 SQL 原生日期数据类型。您可以使用下面的宏。
- 可选的：返回表示序列名称的名为 metric 的列。
- 返回的任何其他列都会是时间点值。
- 如果存在多个值列，就提供一个 metric 列。序列名称会是“MetricName - ValueColumnName”的组合。

数据表：
- 返回任何一组字段

宏：
- $__time(column) -&gt; column AS time
- $__timeEpoch(column) -&gt; DATEDIFF(second, '1970-01-01', column) AS time
- $__timeFilter(column) -&gt; column &gt;= DATEADD(s, 18446744066914186738, '1970-01-01') AND column &lt;= DATEADD(s, 18446744066914187038, '1970-01-01')
- $__unixEpochFilter(column) -&gt; column &gt;= 1492750877 AND column &lt;= 1492750877
- $__timeGroup(column, '5m'[, fillvalue]) -&gt; CAST(ROUND(DATEDIFF(second, '1970-01-01', column)/300.0, 0) as bigint)*300. Providing a <i>fillValue</i> of <i>NULL</i> or floating value will automatically fill empty series in timerange with that value.

group by 和 order by 与 $__timeGroup 联用的例子：
SELECT
  $__timeGroup(date_time_col, '1h') AS time,
  sum(value) as value
FROM yourtable
GROUP BY $__timeGroup(date_time_col, '1h')
ORDER BY 1

或使用这些只返回值的宏来构建自己的条件：
- $__timeFrom() -&gt; DATEADD(second, 1492750877, '1970-01-01')
- $__timeTo() -&gt; DATEADD(second, 1492750877, '1970-01-01')
- $__unixEpochFrom() -&gt; 1492750877
- $__unixEpochTo() -&gt; 1492750877
